. LewisE. Durrin, San Josa o lifq g Application January 23, 1933,'Serial"No. 653,143 I 4 Claims. (01'. r le- 04 My invention relates to improvements in atof the axis of the cylinder. The strips 6 and tachments for paring knives, and it consists of the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide an attachment for a paring knife which is an improvement of the form of the device shown in my co-pending application, filed August 18, 1931,

bearing Serial No. 557,876. The improvement consists in the simplifying of the structure of the attachment so that it can be formed from one piece of material. A further advantage lies in the novel way the attachment is anchored to the knife so that it becomes a permanent part thereof. The device is durable and. eflicient for the purpose intended.

Other objects and advantages will appear in the following specification, and the novel features of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming a part of this application, in which Figure 1 is a side elevation of the knife show- '25. ing the attachment applied thereto;

Figure 2 is a top plan view of the knife showing the attachment in position;

Figure 3 is a development of the piece or blank that goes to make up the attachment; and

Figures 4, 5 and 6 are front, rear and perspective views respectively of the attachment.

In carrying out my invention I make use of a knife that is designed primarily to halve apricots. The knife has a blade portion 1 and a handle portion 2. The purpose of the attachment shown at 3 is to remove the stem end or eyes of apricots, and preferably prior to the slicing operation. The attachment is positioned between the blade and the handle where it is ready for instant use. It will be noted that the attachment does not interfere with the use of the blade. In this way the same handle can be used for halving fruit and for removing stem ends.

In Figure 3 I show a piece of metal 4 which has a cut 5 therein defining two strips 6 and '7. The strip 6 is longer than the strip '7 for the purpose hereinafter described. A slot 8 is cut in the body portion 9 of the material, and forms a tongue 10. The bottom edge 11 is sharpened receive'the knife blade 1 therebetween .The ,portion' 13 of the strip 6 that projects beyond the strip? is bent at right angles and bears against the top edge of the blade 1. This portion acts as an anchoring means and prevents angular movement of the attachment with respect to the blade and handle.

The tongue 10 is bent inwardly so as to contact with the inner rear surface of the cylinder 12 in the manner shown in Figures 1 and 6. The cylinder 12 forms the cutting edgell into a circle and this edge is used for removing stem ends of apricots.

The handle 2 has its end, disposed adjacent to the blade 1, slotted as at 14, and this slotted portion receives the strips 6 and '7; The portion 13 is now bent over into the position shown in Figures 4 and 5. One of the nails 15 that secures the blade 1 to the handle 2 also bears against the rear edges 16 of the strips 6 and 7. This prevents movement of the attachment further into the handle.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

The attachment is prevented from moving upwardly with respect to the knife in Figure 1 because the bottom edge of the blade 1 contacts with the bottom of the cut 5. Angular movement of the attachment with respect to the knife is prevented by the portion 13, and rearward movement of the attachment along the handle is prevented by the nail 15. In this way the attachment is firmly anchored in place.

The cutting end 11 is placed on the apricot so as to encircle the stem end and then the knife is given a slight twisting movement, while at the same time the attachment is forced into the fruit. This causes the stem end to be severed from the fruit and to enter the interior of the cylinder 12. As successive stem ends are received in the cylinder the others will be forced out from the cylinder by means of the tongue 10. There is no chance for the stem ends to become wedged in the space above the tongue and in the cylinder because the tongue is formed from an integral part of the material, and the cut 5 does not extend down into the tongue, see Figures 3, 4 and 6. After the apricot has been stemmed, it is halved in the usual manner for allowing the stone or pit to be removed.

While I have shown only the preferred form various changes or modifications may be made 2. An attachment for a paring knife having a blade and a handle comprising a cylindrical portion having an opening in its side, a tongue extending from one side of the opening down into the cylinder and contacting with the inner cylinder wall disposed opposite to the opening, integral strips extending from the cylinder and x n in parallel w th each th r, said st ips in i ned to straddle the kn f lade, one of th r ps pr jectin b yond the other, the projecting portion being bent for contacting with one edge of the blade.

3. A paring knife attachment comprising a cylindrical portion with sharpened edge, upstanding integral strips extending from the cylinder and designed to straddle a knife blade, one of the strips being bent over an edge of the blade, the cylindrical portion having an opening in its side, and an integral tongue extending from an edge of the opening inwardly into the cylinder and at an angle, the end of the tongue contacting with the innersurface of the cylinder and facing the sharpened edge.

4. The combination with a paring knife having a slotted handle and a blade having a shank received in the slot of an attachment having a body and parallel portions projecting therefrom, the body of the attachment bearing against one edge of the blade while the parallel portions straddle the blade within the slot so as to be confined between the blade and the handle material, one of the portions being bent over the oth r dge of the bl de for firml holdi g t atta hmen in pes en, 1 a
